TOOL-SHARPENING IMPLEMENT.

To all whom it may concern Be it known that I, Gnonen H. J OHNSON, acitizen of the United States, residing at Rose Hill, in the county ofOnondaga and State of New York, have invented new and usefulImprovements in Tool-Sharpening Implements, of which the following is aspecification.

An object of the invention is to provide a device for sharpening tools,such as scissors, knife blades, needles and the like.

My invention resides more particularly in an integral piece of material,preferably madeof carborundum or a similar substance and adapted forsharpenin shears and various other tools.

Reference is to be had to the accompanying drawings constituting a partof this specification, in which similar characters of reference denotecorresponding parts in all the views, and in which:

Figure 1 is a perspective View of my device, a pair of shears beingshown in sharp ening position in dotted lines, Fig. 2 is a verticallongitudinal sectional view.

Referring more particularly to the views, I provide a body 10,preferably made of carborundum or the like and having a longitudinallyextending V-shaped slot 11 formed in the rear end thereof, a series ofperipherally extending grooves 12 being provided on the body at a medialportion thereof. The body 10 at one end thereof terminates in aperipherally extending beveled portion 13 and formed integrally on thebody and oflset from the horizontal axis thereof is a beveled head 14;,the said head being arranged to provide a fiat surface 15 on the upperside of the body 10 and a fiat surface on the lower side of the head14:, the bevel of the portion 13 and the bevel of the head 14 beingadapted to converge, between the top and bottom of the body 10.

When it is desired to sharpen a pair of shears or the like, thementioned shears are engaged with the body 10 and the head 14: so thatthe fiat sides of the shears will abut against the flat surfaces 15, 16while the beveled portions of the shear blades will abut against thebeveled portion 13 and the Specification of Letters Patent.

Application filed October 24, 1911.

Serial No. 656,394.

bevel of the head 14. The handles of the shears are now grasped andoperated to actuate the shear blades in a cutting manner similar to theoperation of the blades in cutting cloth or the like, and the mentioned.movement of the shear blades against the beveled surfaces of the body 10and head 14: will result in the sharpening of the blades, as will bereadily understood.

When it is desired to sharpen sewing needles and the like, the needlesare disposed in the grooves 12 and by'holding the needles rigidly in onehand and the body 10 in the other and moving the body 10 back and forthto frictionally engage the same with the needles, the points of theneedles will readily become sharpened.

In a similar manner a knife blade can be inserted in the V-shaped slot11 and by moving the body 10 back and forth on the knife blade, thementioned blade will become sharpened, it being understood that thematerial from which the body 10 is made is of superior hardness to theusual steel employed in the manufacture of knife blades, needles, shearsand other tools.

I claim 1. A device of the class described comprising a body providedwith peripherally eX- tending grooves and having a V-shaped slot form-edin one end thereof, the other end of the said body terminating in abeveled portion and a beveled head integrally formed on the said otherend of the body, the said head bein offset from the longitudinal axis ofthe body to present a portion of the flat end of the body and a port-ionof the flat end of the head.

2. A device of the class described comprising a body provided with abeveled portion at one end thereof and a head integrally formed on thebody to present a flattened surface of the said body and a flattenedsurface of the said head.

In testimony whereof I afiix my signature in presence of two witnesses.

GEORGE H. JOHNSON.
